Implementation of PWM Speed control for SRM drive using TMS320F28069 Microcontroller

Switched reluctance motors (SRMs) are a promising alternative to conventional motors in various variable speed applications due to their simple design, low production costs, high starting torque, wide speed range, high reliability, and efficiency. However, they suffer from high torque ripple and system noise, which can be minimized by selecting appropriate control methods and converter topologies. Due to the intricate nature of the control, motor drives may employ digital systems by utilizing high-speed digital signal processors (DSPs) or microcontrollers (MCUs) to achieve superior results which offers the flexibility to implement complex control algorithms with high precision and accuracy. Therefore, this study proposes the implementation of a Voltage PWM control strategy for a Switched Reluctance Motor (SRM) on a compact high-speed microcontroller (TMS320F28069) using Code Composer Studio. This study demonstrates how MCUs can aid in the precise control of SRMs.
